Heart Institute Cardiologist in Hot Springs Implants Smallest Pacemaker
CHI St. Vincent Hot Springs announced that it is now one of the first hospitals in Arkansas to offer the world’s smallest pacemaker for patients with bradycardia.
The Micra® Transcatheter Pacing System (TPS) is a new type of heart device, approved for Medicare reimbursement, that provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker. The first procedure was performed by Dr. Srinivas Vengala on September 26, 2018.
Comparable in size to a large vitamin, cardiologists at CHI St Vincent Hot Springs have elected to use Medtronic’s Micra TPS because unlike traditional pacemakers, the device does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy. Instead, the device is small enough to be delivered through a catheter and implanted directly into the heart with small tines, providing a safe alternative to conventional pacemakers without the complications associated with leads – all while being cosmetically invisible. The Micra TPS is also designed to automatically adjust pacing therapy based on a patient’s activity levels.Dr. Vengala says “This technology is a great option for our population in Hot Springs. The decreased risk of infection makes this product a great option in some select patients that only require a single lead pacemaker. I am very excited to be involved in this great technology.”
The Micra TPS also incorporates a retrieval feature to enable retrieval of the device when possible; however, the device is designed to be left in the body. For patients who need more than one heart device, the miniaturized Micra TPS was designed with a unique feature that enables it to be permanently turned off so it can remain in the body and a new device can be implanted without risk of electrical interaction.
The Micra TPS is the first and only transcatheter pacing system to be approved for both 1.5 and 3 Tesla (T) full-body magnetic resonance imaging (MRI) scans and is designed to allow patients to be followed by their physicians and send data remotely via the Medtronic CareLink® Network.
The Micra TPS was approved by the U.S. Food and Drug Administration in April 2016, and has been granted Medicare reimbursement, allowing broad patient access to the novel pacing technology.
Other locations in the CHI St. Vincent Heart Institute will also begin implanting this new device.
